I think it was Vox that ran a short little blurb explaining Republican support for the ACA by pointing out that the majority of Republicans in the House have no credible threat from the left but are deathly afraid of being primaried from the right. In other words, they'd rather be seen as crazy by whatever handful of Democratic voters they might theoretically have to worry about than seen as not crazy enough by whatever deep-pocketed American Enterprise Institute free-market American Taliban tea party militia wants to replace them with Michele Bachmann. Because let's be honest. You weren't gonna vote for a single one of those fuckers anyway. Your scorn and condescension is not a threat to them. '80s kids may recognize this narrative: Yup. John Cornyn thinks the Soviets grew up to be Democrats.
